Overview
The LIS2DS12USTR, produced by STMicroelectronics, is an ultra-low-power, high-performance three-axis linear accelerometer belonging to the "pico" family. This accelerometer leverages robust and mature manufacturing processes used for micromachined accelerometers. It is designed to measure accelerations with user-selectable full scales of ±2g, ±4g, ±8g, and ±16g, and it supports output data rates from 1 Hz to 6400 Hz. The device features an integrated 256-level first-in, first-out (FIFO) buffer and embedded self-test capability, allowing users to check the sensor's functioning in the final application. The LIS2DS12USTR operates over an extended temperature range from -40 °C to +85 °C and is available in a small thin plastic land grid array (LGA) package.
